mplsInterfaceAvailableBuffer
Module: MPLS-LSR-MIB
OID (symbolic): MPLS-LSR-MIB::mplsInterfaceAvailableBuffer
OID (numeric): 1.3.6.1.3.96.1.1.1.9
Node type: OBJECT-TYPE
Type: MplsBufferSize
Access: read-only
Description: This value reflects the total amount of buffer space available on this interface. This variable is not applicable when applied to the interface with index 0.
What is mplsInterfaceAvailableBuffer?
This read-only MplsBufferSize value reports the amount of buffer space currently free on this interface for MPLS-labeled traffic, and does not apply to the special interface with index 0. An admin compares this to mplsInterfaceTotalBuffer to detect buffer exhaustion, which typically precedes packet discards reported in mplsInterfaceInDiscards or mplsInterfaceOutDiscards. A value trending toward zero on a heavily loaded LSR interface would prompt an admin to investigate traffic engineering or QoS adjustments before drops start occurring.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.3.96.1.1.1.9 snmpwalk -v2c -c public <target> MPLS-LSR-MIB::mplsInterfaceAvailableBuffer
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.3.96.1.1.1.9.1 snmpget -v2c -c public <target> MPLS-LSR-MIB::mplsInterfaceAvailableBuffer.1
